Improvement in calendars



UNITED STATES PATENT OFFICEo ALEXANDER C. ADAMS, OF CAMBRIDGE, MASSACHUSETTS.

IMPROVEMENT |N` CALENDARS.

Speciiication forming part of Letters Patent No. 189,832, dated April 24, 1877; application filed February 20, 1877.

r To all whom it may concern Be it known that I, ALEXANDER C. ADAMS, of Cambridge, of the county of Middlesex and State of Massachusetts, have invented a new and useful Improvement in Calendars; and do hereby declare the same to be fully described in the following specification and represented in the accompanying drawings, ot' Which- Figure l represents a front view, and Fig. 2 a transverse section, of one of my improved calendars.

My invention in one sense is an` improvement in the calendar composed of a series of leaves fixed to a hanger, each of such leaves having printed upon it an advertisement and a table ofthe days of each week and the number of days in a month.

With such a calendar it is customary to tear off each leaf after the month to which it may belong may have expired, such being to bring into view the next leaf, representing the days ofthe succeeding month. This in the end effects the destruction ofthe calendar, whereas my improved calendar remains intact, while in use, whereby any one of its pages can be consulted at any time during the year.

In carrying out my invention I combine with a supporting-card, slotted as hereinafter explained, a series of leaves having printed upon them a series of monthly tables, each being indicative ofthe name of a`month, the days of the week, and the days in such month, as in ordinary calendars.

In the drawings, A denotes the advertising and calendar-supporting card or plate, which has made through it two parallel slots, a b,

between which there is fixed to the plate the calendar or book B, which is attached at its middle or back to the plate or card.

The distance between the two slots is to be less than twice the width of the book, in order that when the book is open some of its leaves at their edges may be inserted in one slotand the rest in the other slot, in which case the slots will serve to hold the book open.

The rst and last leaf of the book or either may be pasted to the c'ard. That part of the card which may be above the book may be used for printing onit one or more advertisements.

Instead of slots in the card I sometimes" substitute loops or pockets to receive`"the leaves of the hook, such devices bei'iig mechanical equivalents for the slots.

I do not claim a calendar composed of two separate backs, a series of leaves, and a wire hooked or bent so as to constitute a connection of the backs and leaves, all heilig as represented in the United States Patent No. 126,481.

I claimp As a new or improved article of manufacture, the calendar, substantially as described, composed of the slotted advertising card or plate and the calendar-book or series of leaves iixed to such card or plate, and arranged with its slots essentiallyin the manner and for use therewith, as explained.

ALEXANDER C. ADAMS.
